Scott was born in Perth in 1957 and is the eldest of four siblings with a white mother and an Aboriginal father.

Scott has written three novels and a children's book, and has had poetry and short stories published in a range of anthologies. He began writing shortly after becoming a secondary school teacher of English. His teaching experience included working in urban, rural Australia and in Portugal. He spent some time teaching at an Aboriginal community in the north of Western Australia, where he started to research his family's history.

His first novel, True Country, was published in 1993 with an edition published in a French translation in 2005. His second novel, Benang, won the WA Premiers Literary Award 1999, the Miles Franklin Award 2000, and the RAKA Kate Challis Award 2001. Both novels were influenced by his research and seemed to be semi-autobiographical. The themes of these novels have been described as, "explor[ing] the problem of self-identity faced by light-skinned Aboriginal people and examine the government's assimilationist policies during the first decades of the twentieth century".

Scott was the first indigenous writer to win the Miles Franklin Award for Benang, which has since been published in translation in France and the Netherlands.

His book, Kayang and Me, was written in collaboration with Nyoongar elder, Hazel Brown, his aunt, and was published in May 2005. The work is a monumental oral-based history of the author’s family, the south coast Nyoongar people of Western Australia.

His latest novel That Deadman Dance (Picador, 2010) explores the lively fascination felt between Noongar, British colonists and American whalers in the early years of the 19th century.

Scott lives in Coolbellup, a southern suburb of Fremantle, Western Australia, with his wife and two children.
